HVAC Fan Speed - Weird

I wouldn't call the install simple, mainly because there is very little space to work with (passenger console side). You will need to remove the glove box and loosen another gizmo to gain access to the resistor. Oh, there is also an air duct in front of everything! Whole thing took me a couple hours because I managed to replace it by working around the air duct (instead of removing). I took some pics if you are interested.

Mr Krod, you can not even imagine how helpful your DIY post is. Damned thing just went on my '01 M3, which I just bought 2 days ago. No warranty of course. Thanks again, now I know what to do.

To all who are interested: these things are available from

(supposedly free shipping) I just ordered one. let's see what happens.

Cheers

I just changed mine and was confused on the location. For those doing this themselves look down by the carpet as far forward on the pass. side as possible; once the glove box and kickplate with the floor light is removed. It is not up towards the radio as I thought it was from the pictures. I removed my radio and removed the heater vent and it was not really becessary. The hearter vent reinstalled easier then it was removed. I thought I was screwed when I took it out, but it went in easy. On my car there is a small actuator that is attached to a metal rod that looks like it activated the flap for the lower heat vents. This needed to be removed by 2 T20 Torx screws then I could get at the actual FSR.

All in all 1 hour;s time and a scraped wrist

Thanks to Mr. Krod I am reporting another American Success story - fan is fixed as described. $62 for resitor block, 1 hr of time and a sprained neck - and everything works like new.

Thanks again.

I have both screw holding the resistor in but can not get the resistor OUT!!

THE component in front is blocking it!!

PLEASE HELP!

Got it out...the old resistor is a ***** to get out....be prepared wiht needlenose and a flathead screwdriver for the clip that holds it in place.

There are 4 screws to remove. 2 for the thing in frnt and 2 for the resistor.

Both T-20's I believe

Just to inform anyone who will be needing the FSR... Pacific BMW says they no longer will be selling parts online (except for accessories)... So I ended up having to buy it from my local BMW dealership for 92.00 +tax.

Marknoir,

Was this an OEM BMW part from http://www.carpartsteam.com ?

It looks like I'm going to have to but this too.

Nice DIY, I just replaced the FSR, pain in the ass, but its done.

I think that metal tube you didn't know the name of is the heat controller, there is a sylenoid below it that actuates a door, thats what controls the temp, just a heads up.

This was a great thread. The pictures were absolutely perfect (at least for me). They look exactly like what I saw. I changed my unit out and now the HVAC works fine. Thanks again for saving me a ton of bucks.

BTW: I bought my from Pacific BMW just last week and they are still taking orders for the parts via their website. They do charge 15 bucks for shipping/handling though. But I guess it was worth it for me because I bought a micro filter, oil, and air filter too and it all came to 17 bucks shipping/handling.

I see many threads on the Final Stage Resistor but never any comments on weather or not its auto or manuel climate control. My car has the knobs and I would like to know if both cars have the Final Stage Resistor or is it only the cars with the Auto Climate Control.

Thanks

I believe it's only for cars with AutoClimate control

If you look here
https://www.autohausaz.com/search/pr...stor/Regulator

you can see they say it's only for autoclimate

Fixed it for me, thanks.

That thing blocking the FSR is the Air Distribution Motor...Thanks for the pics!
Just finished not hard repar just a pain in the A$$!

The job was a real pain in the neck....literally! The FSR now replaced. Cost 58GBP from the stealers in the UK. The Auto Climate Control now working as it should. Just in time for the UK hot weather. Many thanks to all of you. Especially to "krod328Ci" for providing pics and instruction.

What is the part number for the Final Stage Resistor (FSR)? I read through the posts but I must have missed it...

anyone?

Here is what I've got...
2001 325ci Auto Climate control, that goes sparatic and wild whenever it wants...

thanks!

Thanks for your wonderful writeup and pictures. For some reason I couldn't find this procedure in the TIS, so this thread was a lifesaver.

For those interested, the part number for the Final Stage Unit is 64 11 6 920 365, the OEM unit is made by Behr. You can get a non-BMW-branded version of the exact same unit from PelicanParts.com for $53.00 plus shipping.

Also, for what it's worth, my car did not have any screws holding the FSR in place. 2001 330xi, January 2001 build.

Does anyone know if the parts from this web site are OEM?
